Hi everyone 

I have a delta VFD ,it's control analog signal is 0..10v

My CPU is 1215c

in order to use the motion control ,is't a must that both CPU and VFD should work with -10..10v

Hello,

Unfortunately your 1215 CPU have only 0-20mA analog output link too see HERE

So solution will be  to add to CPU analog module 6ES7 232-4HB32-0XB0 witch keep +- 10 V

Or use your internal CPU analog output 0-20mA and connect to your DELTA to ACI contact wich read 4-20mA

Or last solution put 500 Ohm resistor and 0-20mA will convert to 0-10V

add attachement for DELTA analog inputs
